Abstract
A simple 1.5 V rail-to-rail CMOS current conveyor is presented. The circuit is developed based on a complementary source follower with a common-source output stage. The circuit is designed using a 0.13 μm CMOS technology and HSPICE is used to verify the circuit performance. The current conveyor exhibits low impedance at terminal X (7.2 Ω) and can drive ±0.6 V to the 300 Ω with the total harmonic distortion of 0.55% at the operating frequency of 3 MHz. The voltage transfer error (between the Y and X terminals) and current transfer error (between the X and Y terminals) are small (-0.2dB). The power dissipation and bandwidth are 532 μW and over 300 MHz, respectively. © World Scientific Publishing Company.
